My 1990 Kenmore model 9113042992 gas wall oven has obviously gone through engineering changes that have resulted in use of different, incompatible parts, for different serial number production runs. I ordered an igniter for this oven and found that the Sears recommended part was a Norton flat style. Partselect.com also pointed to the same flat style. My 9113042992 uses the round carborundum type. I finally tracked down the right part as GE p/n WB2X9154
by surfing the web. My current concern, is, now I've got a bad control board. Engineering changes could have also been made to the control board. Since the latest igniter wouldn't fit my oven, the latest control board may not fit, as well. How can I get the proper control board if the online parts vendors don't publish the different parts, for each serial number production run, for a model that's been in production for an extended period?
